## What it is
The Telomere-to-Telomere (T2T) consortium's complete telomere-to-telomere assembly of the CHM13hTERT human cell line, including the T2T-CHM13v2.0 release with a finished chromosome Y. The repository distributes assembly FASTA files, raw sequencing datasets (PacBio HiFi, Oxford Nanopore, 10X, BioNano, Hi-C), and UCSC genome browser hubs.

## Use cases
- download a complete telomere-to-telomere human reference genome
- get raw PacBio HiFi and Nanopore reads for the CHM13 cell line
- use T2T-CHM13 as a reference for read alignment and variant calling
- view the T2T assembly in the UCSC genome browser
- study human centromeres and repetitive regions missing from GRCh38
- access a complete human chromosome Y sequence

## When to choose
- you need the most complete human reference genome including repetitive and centromeric regions
- you want raw long-read sequencing data for the CHM13 cell line
- you are benchmarking assemblers or aligners against a gapless human reference

## When to avoid
- you need a clinical reference genome with broad annotation support - GRCh38 remains the standard
- you want software or analysis pipelines rather than data
- you need a diploid or diverse pangenome reference - consider the Human Pangenome Reference Consortium instead
